  M45 is IT - 2006 Infiniti M45
  By bsouth808 - September 27 - 4:06 am

  This is the car to own if in the market for something under 60,000. I drove the RL, the BMW 530, and believe it or not the Corvette. Though the Corvette was nice it was not really practicable for the family situation. The power this thing has beats any others in the same bunch. With the Acura everything is standard, but there are no options to get. This thing I have has the DVD player in the roof and on the dash. With rear wheel drive you have no need for SH-AWD. It has a camera for backing up, and trust me if you have never seen this check it out. Intelligent cruise control another thumbs up it really works. Lane changing thingy needs some work. Headlights WOW. POWER POWER POWER

  Best yet - 2006 Infiniti M45
  By WILLIAM B COSTELLO - June 14 - 6:40 pm

  This is my seventh infiniti and the second m45. This one looks and handles much better than my first one. 335 Hp no way this engine puts out a lot more then 335 hp. The voice stuff takes getting used to. The navigation system is the best ive ever used and very easy. My wife liked the car so much she bought a m35x. The fit and finish are perfect

  Best Performance Luxury Sedan - 2006 Infiniti M45
  By shmang - February 22 - 2:40 pm

  This car is simply amazing. With the luxury and performance combined together, few can match. Infiniti gets it just right. It is packed with luxury options to make it a true luxury car, while the 335hp V8 with firm suspension makes the car a true performer. It is not a sports car for sure, which it should not be, as it is a luxury sedan. This car makes the trip enjoyable no matter drive it fast or slow.

  Expensive: Low Quality Features - 2006 Infiniti M45
  By dembinsk - December 13 - 4:43 pm

  I have owned a 02 BMW 330 sport sedan, a 03 BMW 540 sport manual 6 speed, and finally decided to give the japanese a try. The Infiniti M45 is by far the closest feel to the germans you can get in a japanese sports sedan. Great reliability, great styling, and many features. Problem with the car is the horrible gas mileage averaging 13.5 MPG in the city and thats 3.4 MPG less than my BMW 540. Tons of features but they are all low grade. For example..the seat heaters dont even compare to the BMWs, the sound system is very hollow and tin sounding (plastic like), shared dashboard gauges from the Altima, and last...the suspension is horribly rough on everyone in the car.

  Great Car - 2006 Infiniti M45
  By bob foster - November 12 - 11:00 pm

  The M45 Sport has met my expectations which were high to start with. It is both beautiful and a terrific driving experience. Number one would be the engine and drive train. Best feel of power and control I have ever experienced including BMW540i. It is both design and crafted with excellence and thought. The technology is very good but not quite up to the Acura RL, but I would take the drive train and vehicle design over the technology difference. The features are very extensive and user friendly. One can practically live in the car enjoying all the features and technology. It handles very well at all speeds and conditions as all the reviews showed. I have not been disappointed.

  06 M45 Luxury Muscle Car - 2006 Infiniti M45
  By Silk - October 14 - 4:30 am

  06 M45 non-sport journeyman off lease 32k miles. So much fun to drive you just don’t want to get out. Powerful and smooth acceleration at all speeds. All controls are easy to operate. I’m 6’4 & fit very well in terms of head and leg room. The M45 was the right combination of power, ride quality and technology goodies for me. The Bose sound system is wonderful. The M45 sport was just too stiff a ride for me. The M35 does not have the same power, only 1 MPG difference anyway. I bought the Infiniti extended warranty (bumper to bumper) till 100k miles or 2014. Infinity also has the best car loaner program. You always get a loaner (g35) no matter how old or out of warranty your infiniti.

  Must have M45 - 2006 Infiniti M45
  By Denis Valle - August 9 - 11:50 am

  Youll be more than glad to take this car the long way home. Plenty of power throughout the power band.

  Infiniti Mx45 - 2006 Infiniti M45
  By Jan - July 14 - 2:13 pm

  Driving has been a pleasure so far but have not encountered any real adverse weather conditions yet. Have had to have the complete gps system replaced at 3,000 miles. None of the controls would work including the cruise control. Poses a serious threat should you be caught in some inclement weather if you cant defrost your windshield

  Big mistake - 2006 Infiniti M45
  By HAL - July 6 - 7:03 am

  After owning from Porsches (11) to Bmws (4) and various American cars spanning over 45 years, this rates as one of the most overrated and troublesome vehicles I have owned. What makes it worse has been no factory support for these problems, which have been mostly electronics that control safety function such as ABS,Traction Control,Etc.The selling dealer service manager did everything he could to solve the problems, even improvising on his own but was limited by the factory representatives. Back to German cars, forever!
